So, as you can see, we have a set of information between markup tags ( the <thing> ). Your best approach is to cut and paste this into your "templateDetails.xml" file and change the relevant bits (such as <name> <author> ).

The <files> part should contain all the files that you use - you possibly don't know what they are called yet - don't worry update it later.

Leave the positions as they are - these are a common set so you will be able to switch easily from the standard templates.
